Be it known that I, ELIAS I-I. KELLEY, a citizen of the United States, residing in the borough of Manhattan, city, county, and

5 State of New York, have invented a new and useful Improvement in Fraud-Preventive Devices for Vending-Machines, of which the following is a description..

This invention has reference to vending machines of the coin-controlled type, and particularly relates to fraud preventive mechanism for vending machines of any type.

Among the objects of my invention may be noted the following: to provide means by which the machine is prevented from being tripped into action when the coin is not of the proper thickness; to provide means by which the check, intended to operate the machine, can be accurately gaged as a preliminary to the operation of the machine; to provide a device for preventing the coin or check from tilting and, in combination 'with the gaging device, to aid the latter to perform its functions; to provide a vending apparatus making it impossible for the machine to effect the delivery of an article with anything other than a good coin of proper thickness, or a check of predetermined character; to` provide an apparatus with means which will enable the detection of slugs, spurious coins, disks, rings and other things in form similar to a coin.

With the above objects in view and others which will be detailed during the course of this description, my invention consists in the elements, mechanisms, parts and features, and combinations of elements and mechanisms all as hereinafter described and claimed. i

. In order that my invention may be clearly understood, I have provided drawings wherein:

Figure 1 is an enlarged detailed view in longitudinal vertical section of so much of my coin-controlled apparatus as is deemed necessary to illustrate my present invention;

Fig. 2 is a plan view of one of the slide mechanismsshowing my fraud preventing li f device in its operative relation to the coindetecting mechanism of the apparatus, parts being broken away and other parts being in section owing to the character of the figure; Fig. 3 is an end elevation and partial section taken Substantially on the line 3-3 of Fig. l, the supporting plate, however, being omitted from this figure, and4 the arrow indicating the direction of sight; Fig. 4 is a perspective view of one of the coin-slides; and Fig. 5 is a perspective View ofthe bottom of the leveling-plate. Referring to the drawings, the numeral 1 indicates the front-plate of the machine, 2

the supporting-plate, 3 the slide-plate, 4 theing no part o`f my present invention but bey ing claimed in my copending application No. 619,989, filed April 10, 1911, and being the same as that disclosed in my application Serial No. 533,638, filed December 17, 1909, of which this application and my application No. 619,989 are divisions. The juxtaposition of parts of my present invention with reference tothe ram and the tripping-device, generally indicated by 8, is, however, a part of my present invention. A coin-slide retrieving 4and locking mechanism, generally indicated by 9, is also shown in the drawings but forms no part .of my present invention in the matter of its details and is shown in the drawings only to disclose an operative mechanism and identify the maif? chine with that of my afo-resaid-parent a-p` plication.. Also aI slide locking mechanism generally indicated by 10 is shown inthe drawings but 4forms no part of my present invention.

The details of the coin-slide are shown in Fig. 4, and the operative relation of the same shown in Fig. 1, a chute 12 coperating with said aperture. The said coin-slide is` provided with three parallel grooves 13, -14 and 15, Fig. 4, divided substantially centrally by a coin-receiving aperturel 16. The central groove 14 extends from a point a short distance from the front end of said. slide to i near its rear end. The groove 13 extends from the rear end of the slide to within a j at its rear end beside the stantially that of the coin.

short distance of the front end of the groove 14. The groove 15 extends from the same point at the front end of the slide as the groove 13, to the rear end of the slide, which, at this side, is cut out to provide the angular recess 17. The slide on its left side, groove 15, is provided with a lug 18, having its front face inclined, as at 19, to form a cam-surface. The rear end of the slide, on its right side beside the groove 13, is provided with a V-shaped transverse notch 20 having no reference to my present invention. The diameter of the coin-receiving aperture 1l will be just' sufficient to admit the coin for which it is intended. The coin-slide 4 is dove-tailed into the slide-holder 3 and is moved forward in said holder manually by the knob 5, screwed into an aperture at the front end of the slide, as at 21. The return movement is caused by retrieving mechanism 9.

A. device for -preventing the coin from tilting in the coin-slide and carried by the slide-'plate 3 operates in conjunction with the coin-slide just described. It consists of a plate 22, Figs. 1, 3 and 5, having opposite lateral extensions -23 at rest on opposite sides of and secured to the slide-plate, by means of screws 24,'passing through said plate 22 into the said slide-plate, said plate 22 being provided centrally with a longitudinal slot,r25 and, on opposite sides of said slot with longitudinal depending ribs 26 and 27, which enter, respectively, the grooves 13 and 15 of the coin-slide and have their forward ends upwardly curved at 28 so as to freely admit the edge of the coin thereunder. The slot 25 registers with the central groove 14 of the coin-slide. The location of this plate 22 is in rear of the coin-receiving aperture 16 and a short'distance'in rear of the faceplate 1 of the frame. It extends rearwardly substantially to the coin-escape aperture 11,y

Fig. 1, and the ribs 26 and 27 extend to substantially the bottom of the grooves 13 and 15, which latter are in depth sufficient to have their bottom surface substantially flush with the surface of a coin inserted in the coin-aperture 16, the thickness of said slide below the bottom of said grooves being. sub- Thus, with the c'oin in place in the coin-slide, it will be prevented from being tilted relatively to the slide, as the latter is moved forward, since the edge of the coin will `slide freely under the ribs of the plate and will be properly presented to a coin-gage and detector which will bepresently described. This anti cointilting plate is an important feature of my invention since, by preventing the coin from tilting in the coin-aperture 16, said coin will be properly passed forward to undergo certain'tests described, and said plate 22 acts positively to depress, if necessary, the coin in its slide andhold it therein.

As a preliminary detector, l have provided a thick-coin detector, or means for preventing a coin, having a greater thickness than the proper thickness of a good com, from being pushed into the machine by the slide. This means consists of a depending is aided by beveling the functional end thereof as indicated by 31, viz., rearwardly and upwardly; that is -to say, with a front edge only in coperative relation to the groove 14 of the coin-slide the position of the finger can be set without fear of any portion in rear of said edge interfering with the coin.

Should the thickness of the coin inserted in the coin-aperture 16 be less than that of a good coin, thus enabling the coin to pass the linger 28, I have provided gaging means controlled by the coin and operating upon the slide to prevent the latter from being pushed in to operate the machine. detector consists of the anti-friction roll 32 having its journal 33 extending through its carrier 34 and into the side-bars 35 of a frame or truck, the front ends of which sidebars extend between lugs 36 fixed to the opposite sides of the slide-plate 3 and journaled in said lugs by means of the pin 37, on which is also journaled the rear end of the carrier 34.

The rear or cross-bar 38 of the truck has extending from it a pin 39, which is screwed thereinto and which pin carries a stopdevice 40, having a laterally extending portion 41, through which extends vertically a stop-pin 42, the lower end of which is beveled rearwardly and upwardly and which pin may be adjusted vertically by threading the same into the portion 41, as clearly indicated in Fig. 1. The stop-device 40 is adjustable on the pin 39, both circum ferentially and longitudinally, by means of the screw 43, passing through said device and engaging said pin. The laterally-extending portion 41 disposes its pin 42 with its lower beveled end, directly in line with the lug 18 on the rear end of the coin-slide 4, so that, if a coin placed in the coin-slide be thinner than a good coin, and should pass the thick-coin finger28 and Vthus pass under the roll 32,*the latter will not be lifted, or not suliciently lifted, and, conse- This thin-coinl quently, the truck will not be lifted, thus.

leaving the pin 42, with its beveled end, directly in the path of the lug 18, which will completely stop the progress of the coinslide rearwardly. If, however, the f coin placed in the coin-slidevbe of the same thickness as a good coin, it will pass the finger 28, the plate 22 andthe roll 32 and lift the latter together with its truck and thus lift'the stop-device, which will carry its stop-pin 42 out of the path of the camstop-device.

The standard 6 is secured to the slideplate 3 and is bored to receive the ram parts 7. The standard 6 is recessed at 44 to receive and permit movement of the rear end of the carrier 34. The standard 6 also carries a rearwardly extending lug 45, recessed to receive thel upper end of a coiled-spring 46, the lower end of which engages the rear bar of the truck 35 and encircles a pin thereon 4and thus normally keeps the truck depressed with its stop-dvice in position such that the pin 42 of the latter will either stop or permit the passage of the coin-slide, as previouslv indicated. The spring 46 is light and aids gravity in one direction, but does not materially impede the raising. of the truck. The periphery of the roller 32 is rounded or U-shaped, as shown in Fig. 1, or may be flat as shown in YFig.- 3, these shapes given to the periphery/of the roller being in contradistinction to a V-shaped edge or periphery, since thefunction of the roller is to feel and sensitively gage a coin as it passes thereunder and not to mark, score or impede the progress of the coin. For the same reason the spring 46 is made very light so as not to impose upon the coin, through the roller, anexcessive pressure. This is an important point, since the more sensitive the gage is the less impediment it will impose-to the passage of the coin-slide, which, .for this gaging operation, should be permitted to move freely.

If the forward end of the coin-slide reaches the tripping-rod 47 of the tripping mechanism 8 the coin will have passed the magnet stop or lock 48, thick coin-detector 28, anti-coin tilting plate 22 and Vthln colnp detector 32, and will have reached the position of the coin-escape aperturell. In this l position the coin undergoes` a test for tensile strength imposed-upon it by the ram-` head 49 of the testing mechanism 7 working-1in the standard 6.

aving thus described my invention what .'I claim and desire to secure by Letters Patent is: l
